Python 3.11 3.11.2 다운로드

Core and Builtins

- gh-101037: Fix potential memory underallocation issue for instances of int subclasses with value zero.
- gh-100942: Fixed segfault in property.getter/setter/deleter that occurred when a property subclass overrode the __new__ method to return a non-property instance.
- gh-100892: Fix race while iterating over thread states in clearing threading.local. Patch by Kumar Aditya.
- gh-100776: Fix misleading default value in input()’s __text_signature__.

Library
- gh-101541: [Enum] - fix psuedo-flag creation
- gh-101326: Fix regression when passing None as second or third argument to FutureIter.throw.
- gh-100795: Avoid potential unexpected freeaddrinfo call (double free) in socket when when a libc getaddrinfo() implementation leaves garbage in an output pointer when returning an error. Original patch by Sergey G. Brester.
- gh-101143: Remove unused references to TimerHandle in asyncio.base_events.BaseEventLoop._add_callback.
- gh-101144: Make zipfile.Path.open() and zipfile.Path.read_text() also accept encoding as a positional argument. This was the behavior in Python 3.9 and earlier. 3.10 introduced a regression where supplying it as a positional argument would lead to a TypeError.
- gh-101015: Fix typing.get_type_hints() on '*tuple[...]' and *tuple[...]. It must not drop the Unpack part.
- gh-100573: Fix a Windows asyncio bug with named pipes where a client doing os.stat() on the pipe would cause an error in the server that disabled serving future requests.
- gh-100805: Modify random.choice() implementation to once again work with NumPy arrays.
- gh-90104: Avoid RecursionError on repr if a dataclass field definition has a cyclic reference.
- gh-100750: pass encoding kwarg to subprocess in platform
- gh-100689: Fix crash in pyexpat by statically allocating PyExpat_CAPI capsule.
- gh-100740: Fix unittest.mock.Mock not respecting the spec for attribute names prefixed with assert.
- gh-86508: Fix asyncio.open_connection() to skip binding to local addresses of different family. Patch by Kumar Aditya.
- gh-100287: Fix the interaction of unittest.mock.seal() with unittest.mock.AsyncMock.
- gh-100474: http.server now checks that an index page is actually a regular file before trying to serve it. This avoids issues with directories named index.html.
- gh-100160: Remove any deprecation warnings in asyncio.get_event_loop(). They are deferred to Python 3.12.
- gh-96290: Fix handling of partial and invalid UNC drives in ntpath.splitdrive(), and in ntpath.normpath() on non-Windows systems. Paths such as ‘\server’ and ‘\’ are now considered by splitdrive() to contain only a drive, and consequently are not modified by normpath() on non-Windows systems. The behaviour of normpath() on Windows systems is unaffected, as native OS APIs are used. Patch by Eryk Sun, with contributions by Barney Gale.
- gh-78878: Fix crash when creating an instance of _ctypes.CField.
- gh-99952: Fix a reference undercounting issue in ctypes.Structure with from_param() results larger than a C pointer.
- gh-100133: Fix regression in asyncio where a subprocess would sometimes lose data received from pipe.
- gh-100098: Fix tuple subclasses being cast to tuple when used as enum values.
- gh-98778: Update HTTPError to be initialized properly, even if the fp is None. Patch by Dong-hee Na.
- gh-83035: Fix inspect.getsource() handling of decorator calls with nested parentheses.
- gh-99576: Fix .save() method for LWPCookieJar and MozillaCookieJar: saved file was not truncated on repeated save.
- gh-99433: Fix doctest failure on types.MethodWrapperType in modules.
- gh-99240: Fix double-free bug in Argument Clinic str_converter by extracting memory clean up to a new post_parsing section.
- gh-64490: Fix refcount error when arguments are packed to tuple in Argument Clinic.
- gh-85267: Several improvements to inspect.signature()’s handling of __text_signature. - Fixes a case where inspect.signature() dropped parameters - Fixes a case where inspect.signature() raised tokenize.TokenError - Allows inspect.signature() to understand defaults involving binary operations of constants - inspect.signature() is documented as only raising TypeError or ValueError, but sometimes raised RuntimeError. These cases now raise ValueError - Removed a dead code path
- gh-95882: Fix a 3.11 regression in asynccontextmanager(), which caused it to propagate exceptions with incorrect tracebacks and fix a 3.11 regression in contextmanager(), which caused it to propagate exceptions with incorrect tracebacks for StopIteration.
- bpo-44817: Ignore WinError 53 (ERROR_BAD_NETPATH), 65 (ERROR_NETWORK_ACCESS_DENIED) and 161 (ERROR_BAD_PATHNAME) when using ntpath.realpath().
- bpo-40447: Accept os.PathLike (such as pathlib.Path) in the stripdir arguments of compileall.compile_file() and compileall.compile_dir().
- bpo-36880: Fix a reference counting issue when a ctypes callback with return type py_object returns None, which could cause crashes.
Documentation
- gh-100616: Document existing attr parameter to curses.window.vline() function in curses.
- gh-100472: Remove claim in documentation that the stripdir, prependdir and limit_sl_dest parameters of compileall.compile_dir() and compileall.compile_file() could be bytes.
- gh-99931: Use sphinxext-opengraph to generate OpenGraph metadata.
Tests

Build
- gh-101522: Allow overriding Windows dependencies versions and paths using MSBuild properties.
Windows
- gh-101543: Ensure the install path in the registry is only used when the standard library hasn’t been located in any other way.
- gh-101467: The py.exe launcher now correctly filters when only a single runtime is installed. It also correctly handles prefix matches on tags so that -3.1 does not match 3.11, but would still match 3.1-32.
- gh-101135: Restore ability to launch older 32-bit versions from the py.exe launcher when both 32-bit and 64-bit installs of the same version are available.
- gh-82052: Fixed an issue where writing more than 32K of Unicode output to the console screen in one go can result in mojibake.
- gh-100320: Ensures the PythonPath registry key from an install is used when launching from a different copy of Python that relies on an existing install to provide a copy of its modules and standard library.
- gh-100247: Restores support for the py.exe launcher finding shebang commands in its configuration file using the full command name.
- gh-100180: Update Windows installer to OpenSSL 1.1.1s
- bpo-43984: winreg.SetValueEx() now leaves the target value untouched in the case of conversion errors. Previously, -1 would be written in case of such errors.
macOS
- gh-100180: Update macOS installer to OpenSSL 1.1.1s

- Do not generate noptargs when there is a vararg argument and no optional argument.
C API
- gh-99240: In argument parsing, after deallocating newly allocated memory, reset its pointer to NULL.
